Incazelo nezici
AmaMolluscs ahlukahlukene kakhulu ngokwezibalo lezi zilwane zihlala endaweni yesibili emhlabeni, eyesibili ngemuva kwamathambo. Zonke izigaba ezintathu zalezi zingenamgogodla zabelana ngezinto ezijwayelekile, ngokwesibonelo, umzimba wazo uvame ukuba nezendlalelo ezintathu, kanti umzimba uqobo lwawo umbozwe "umgubuzelo" wesikhumba obizwa ngokuthi ingubo.
Njengomthetho, lezi zidalwa, ngaphezu komzimba, zinomlenze nenhloko, kepha izinhlobo ezahlukahlukene zingantula ezinye zalezi zinto. Ake sixoxe ngokushesha kakhulu cephalopods yekilasi... Ngokungafani nozakwabo abaningi, lezi zilwane zichitha isikhathi sabo esiningi zihamba.
Ngaphezu kwalokho, ziyashesha impela, zingafinyelela kalula isivinini samakhilomitha angama-50 ngehora. Izilwane zikwazi ukwenza uchungechunge lwezenzo eziyinkimbinkimbi, zihlakaniphe kakhulu phakathi kwezinhlanzi. Amanzi anosawoti olwandle nezilwandle asebenza njengekhaya labo. Ubukhulu buhluke kakhulu, kusuka kusentimitha elilodwa kuya kumamitha amaningana ubude. Abantu abakhulu bangakwazi ukukala cishe isigamu setani.
Izidalwa ezidliwayo eziphakanyisiwe zinesici esiyinhloko esihlukanisayo - izintambo zazo zitholakala ekhanda, zikhawulelana nomlomo. Amayunithi alesi sigaba kuphela aneShell, bonke abanye abenza ngaphandle kwawo.
Kunezinhlobo ezingaphezu kwamakhulu ayisikhombisa zalezi zingenamgogodla. Cishe, ngamunye wethu okungenani kanye wabona i-squid, noma ngabe ayiphili, noma i-octopus. Omunye ummeleli owaziwayo futhi owaziwayo wama-cephalopods yi-cuttlefish.
Ukubukeka kwama-cephalopods kuhluke ngokuphelele. Umzimba wabo ungafana nerokhethi, isikhwama esinezinsiza eziningi, noma ikepisi elinezigqoko.
Ngaphakathi komzimba kungahle kube nohlobo oluthile lwegobolondo, kepha lokhu akuyona neze "indlu" enekhalori njengama-gastropods, isibonelo. Amapuleti azacile, noma izinaliti zelimu nje, ayini umabhebhana esikhundleni segobolondo lolwandle.
TO izici zama-cephalopods kungabangelwa ukuthi lezi zingenamgogodla zinamathambo. Kepha hhayi ngomqondo wethu ojwayelekile, lawa akuwona amathambo. Yakhiwa izicubu ze-cartilage. Ivikela ubuchopho, ifihle izinhlamvu zamehlo, futhi ibuye ifinyelele ezansi kwamathambo namaphiko.
Ngaphandle kokuthi ama-cephalopods yi-dioecious, awahlangani. Lapho owesilisa esekulungele ukuba mdala, enye yezingalo zakhe eziguqukayo iyaguqulwa ukuze kuthathwe amaseli wegciwane emgodini wengubo yakhe futhi awathumele ngokuphepha emgodini ofanayo nowesifazane okhethiwe.
Kukhona indlela ethakazelisa kakhulu yokufaka umanyolo etholakala kwezinye izinhlobo: itende elikhethiwe kowesilisa, eligcwele isidoda, liphuma emzimbeni womninikhaya lingene ekubhukudweni kwamahhala. Lapho esethole insikazi, lesi "sikebhe sothando" singena ngaphakathi emzimbeni wakhe. Kodwa owesilisa akahlali ekhubazekile, omusha ukhula esikhundleni somlenze olahlekile.
Lezi zilwane zizalela amaqanda azo ngokukhethekile. imisele engezansi. Ngaphambi kokuzalwa kwezingane, izinhlobo ezithile zama-mollusk zigada inzalo yazo, kepha sikhuluma ngomama kuphela. Ngokuqapha i-clutch, lesi silwane sikwazi ukusenza buthaka kangangoba uma kufika isikhathi sokuthi izingane zishiye “igobolondo”, umzali wazo uyafa ngenxa yokungabi namandla.
Isakhiwo se-cephalopods
Ngaphandle:
AmaMolluscs abonakala ngokulinganisa. Umzimba wabo uyefana ezinhlangothini ezingakwesokudla nangakwesobunxele.
Imilenze, njengesibonelo, kuminenke, ngeke uyithole kulezi zinkawu. Lokhu kungenxa yokuthi iguquke yaba yibhubhu esisekelweni somzimba kusukela ohlangothini olungezansi. Le siphon isiza isilwane ukuba sihambe ngokushesha, amanzi anqwabelene ngaphakathi abukhali aphuma kuwo bese kuhamba ukunyakaza kwe-jet. Esinye isithasiselo somlenze yimilenze, kukhona okungu-8 noma i-10.
Ingubo, noma isibaya sesikhumba sizungezile umzimba wama-cephalopods... Ukusuka ngenhla, ikhulele kwizembozo zangaphandle, kepha hhayi kusuka ngezansi, ngenxa yalokho kwakhiwe umgodi wengubo. Kunembobo encane esibayeni evumela amanzi ukuthi angene.
Umgodi wengubo awugcini nje kuphela ukuze ukwazi ukuhamba, ukhipha amanzi ngokucijile ngegwababa (siphon), kepha futhi nokuphefumula. Emva kwakho konke, kunezifo. Njengomthetho, kunezimbili zazo, kwesinye isikhathi ezine. Futhi nendunu, isitho sangasese, iphuma iye lapho.
Izindwangu ezinamandla kakhulu zama-cephalopods zigcwele ngokoqobo amaswidi amaningi. Lezi zinzwane eziqinile ekuqaleni zivela emigqeni yonyawo. Njengoba umuntu ekhula, baya phambili futhi bakhe umlomo womlomo.
Izintambo azisebenzi njengemilenze kuphela (okusho ukunyakaza), kodwa futhi njengezandla ezingabamba inyamazane. Kodwa ubuchopho abuvamisile ukuthumela amasiginali athile ezithweni. Ezimweni eziningi, zimane zihambe ngokungahleliwe, zinqotshwe ithonya lamangqamuzana ezinzwa.
Ngaphakathi:
Uma kubamele bezinye izigaba zama-mollusks, igazi ligeleza ngokukhululekile emzimbeni wonke, ligeza izitho, khona-ke uhlelo lokujikeleza kwama-cephalopods - kuvaliwe. Negazi ngokwalo alinawo umbala obomvu, kungathiwa alinambala. Isizathu silula - ayikho i-hemoglobin kuyo.
Endaweni yayo kwaba hemocyanin (iqukethe iminonjana zethusi). Ngenxa yalokho, i-invertebrate yaba "yigazi eliluhlaza okwesibhakabhaka", i.e. ngamanxeba, igazi liphenduka uketshezi oluhlaza okwesibhakabhaka. Isakhiwo senhliziyo simi kanje: i-ventricle eyodwa, ama-atria amabili (ezimweni ezingavamile - 4).
Ingqongqoza ngesivinini esiphindwe kathathu ngomzuzu. I-mollusk ihlukile ngoba inezinye izinhliziyo ezimbili, i-gill. Ayadingeka ukuhambisa igazi ngesistimu yokuphefumula futhi abahlinzeke nge-oxygen.
Ifanelwe ukunakwa okukhethekile futhi uhlelo lwezinzwa lwama-cephalopods... Izilwane zingabizwa ngokuthi zinamasu kakhulu. Izindlala zezinzwa ziyahlangana zakhe ubuchopho obusemqoka. Njengoba sesishilo, ihaqwe ngisho nangohlobo logebhezi.
Yilapho amakhono amangalisayo ama-cephalopods avela khona. Ama-octopus adume kakhulu kuwo. Okokuqala, lezi zidalwa kungathiwa ziyaqeqeshwa. Bakhumbula kahle ukulandelana kwezenzo ezidingekayo ukuqedela umsebenzi esimweni ngasinye.
Isibonelo, bangavula isitsha ukuze bathole into oyifunayo. Uma lowo muntu ebona ukuthi umuntu akakwazi ukubhekana nesimo, kungaheha izihlobo zakhe. Ndawonye bahlakulela wonke amaqhinga wokuzingela.
Ngendlela, i-rectum yalaba banikazi be-tentacle inesici esithakazelisa kakhulu - kunesikhwama esikhethekile lapho. Leli vial linezingxenye ezimbili. Ngezansi - okusanhlamvu okuyisipele kwedayi ekhethekile, phezulu - uyinki owenziwe ngomumo uma kunesidingo.
Futhi uyaludinga lolu ketshezi oluhlaza okwesibhakabhaka ngokunsomi (kwesinye isikhathi kumnyama, nsundu) ukuze uzivikele uma kunengozi. Isembozo esinombala onjalo sizophazamisa isitha. Iveyili emnyama imboza ngokoqobo amanzi amamitha amaningana endaweni. Ngemuva kokukhishwa, lesi "sikhali" sibuyiselwa ngokushesha okukhulu, kwabanye kwanele ngisho nengxenye yehora ukuthi bakulungele ngokuphelele ukulwa.
Kuyathakazelisa futhi ukuthi abanye abacwaningi bakubonile ukufana kwalokhu kukhishwa kukayinki nabaphathi babo kuhlaka. Labo. isilwane sishiya umqubuko onje esitheni, kanti ngenkathi sizama ukusidla, "singathatha izinyawo zaso." Ngaphezu kwalokho, uyinki oyingqayizivele uyakwazi ukuqeda iphunga lenombolo yezinhlanzi ezidlayo.
Futhi ukuthola imizwa yabo yokuhogela, bazodinga okungenani ihora. La madayi nawo awaphephile kuma-mollusk ngokwawo. Ngakho-ke, izilwane zishiya ngokushesha lapho "ifu" lazo likhishwa khona. Ngokuqondene nempilo yabantu, konke kuzolile lapha, uyinki ngeke usilimaze. Ngisho nasekuxhumaneni kwamehlo. Ngaphezu kwalokho, ama-gourmets ayakujabulela ukuwadla.
Lezi zidalwa zasolwandle zizwakala ngomzimba wonke. Phakathi kwezinye izinto, la ma-mollusk anuka kahle, anambitha, futhi abona kahle. Banamehlo amahle kakhulu. Amehlo ngokuvamile makhulu.
Izinhlobo
- I-Fourgill
Iqembu le-cephalopods elilula kakhulu. Ngaphandle kwamagill amane, anezinombolo ezifanayo zezinso ne-atria. Phakathi kwezinye izinto, umehluko wazo ophawulekayo yigobolondo elingaphandle, elihlanganisa cishe wonke umzimba. Bavela emhlabeni wethu eminyakeni engaba yizigidi ezingamakhulu ayisihlanu edlule. Ummeleli oyedwa kuphela walaba abanemizimba ethambile osindile kuze kube namuhla - nautilus.
Igobolondo le-nautilus elinsundu nelimhlophe line-curl evunguza. Ukusuka ngaphakathi, imbozwe ngomama weparele. Iqukethe amakamelo amaningana. Enye yazo isebenza njengendawo yokugcina umzimba wesilwane. Amanye amakhamera ayadingeka ukuze ungene phansi. Uma i-invertebrate idinga ukuya ngaphezulu kolwandle, igcwalisa lezi ziqukathi ngomoya, kepha uma idinga ukuwela phansi, amanzi asusa umoya. Ngokuhamba kwesikhathi sempilo, inani lamakamelo liyakhula.
I-cephalopod ayithandi ukujula okukhulu kakhulu, ikhetha ukungahambi ngaphansi kwamamitha ayikhulu. Lokhu kungenxa yokuthi igobolondo libuthaka ngokwanele, futhi ikholamu lamanzi ngesisindo sayo lingamane nje lephule.
Ukucabangela isakhiwo se-cephalopods, i-nautilus inokucushwa okwenziwe lula ukwedlula abazala bayo. Ingxenye yekhanda nezintambo kuphela ephuma "endlini" yesilwane; inezingama-90 zazo. Njengamanye ama-cephalopods amaningi, lezi zinqubo zinamaswidi, "izingalo" uqobo zinemisipha, evumela umuntu ukuthi azulazule abambe inyamazane ngaphandle kwezinkinga. Kokubili ukudla kwezilwane nezitshalo kuyadliwa.
Ngaphezu kwalokho kunamehlo nomlomo ekhanda. Abesifazane bancane kancane kunabesilisa. Le invertebrate inomqondo othuthukile wokunuka, kepha umbono awubukhali kangako. Ingubo, njengengubo, imboza iNautilus yonke. Iyancipha lesi sitho. Isilwane sicindezela amanzi siphume kuwo, ngaleyo ndlela sihambe kukholamu lamanzi.
Ngokuqondene nokuzala, bavuthwa ngokocansi, bafinyelela cishe kumasentimitha ayi-10 kububanzi begobolondo (ngokuvamile, isilwane singazikhulisela igobolondo ngokwaso no-25 cm ububanzi). Owesilisa ube ebeka amangqamuzana akhe ocansi emzimbeni wowesifazane. Ezinyangeni eziyisithupha kamuva, ama-nautilus amancane aqanduselwa emaqandeni abekiwe, ephinda ngokuphelele isakhiwo sabazali bawo.
Eminyakeni yamuva, inani lalaba bantu liye lehla. Isizathu intshisekelo yabantu eyengeziwe. Ngemuva kwakho konke, igobolondo lesilwane lisetshenziswa njengomhlobiso wokuhlobisa. Ukugcina invertebrate ekuthunjweni kuyabiza impela, ngaphandle kwalokho, lowo muntu uqobo uzobiza umuntu ofuna ukulithenga inani elikhulu.
- Okubili
Njengoba igama liphakamisa, lezi zilwane zinama-gill amabili. Ziyinkimbinkimbi kakhulu kunabamele iqembu langaphambilini. Abanalo igobolondo ekuqondeni kwabo kwakudala. Amabhulethi amancane kuphela ngaphakathi komzimba - yilokho akushiye ngemuva. Izitho zabo zombono zithuthukile impela.
Ibutho ihlukaniswe suborders ezimbili:
- Banezikhali eziyishumi (banamabhangqa amahlanu okuqina, elinye lawo lide futhi lisebenza njengeminwe eqinile).
Ama-squids.
Abantu bazi cishe izinhlobo ezingamakhulu amathathu zama-cephalopods anjalo. Imvamisa, lesi silwane sibukeka njenge rokhethi elide elinezintambo. Ngendlela, azikhuli ndawonye, azikho ulwelwesi phakathi kwazo. Kepha ama-squid aneziphetho ezibukeka njengezimpiko. Lezi zimpiko ezimbili zingaba zikhulu impela, futhi zisebenze njengezinhlobo ezithambile zokuhamba emanzini.
Njengamanye ama-cephalopods, amandla asebenzayo nawo ayabasiza ukuba bahambe, futhi bangashintsha ngokushesha indlela yokuhamba ngosizo lwe-siphon. Ngenxa yekhono lokuyilawula, isilwane sikwazi ukubuyela emuva, futhi size sindiza phezulu ngaphezulu kwamanzi.
Esimweni esizolile, ama-invertebrate awabukeki ehlaba umxhwele kakhulu, umzimba wawo uyakhanya, ubushelelezi, ubomvana, noma umhlophe, kepha unamandla we-phosphoresce enezimbali eziluhlaza okwesibhakabhaka. I-squid ithole leli khono ngenxa yamagciwane athile atholakala emzimbeni wabo. Ngenxa yokukhanya kwawo okukhangayo, i-squid iheha isisulu sayo.
Abantu abancane kunabo bonke bangama-10 cm ubude, kanti ezinkulu zingakhula zifike kumitha elilodwa. Sekunesikhathi eside kunezinganekwane ngezilo zasolwandle ezihlasela imikhumbi yamatilosi. Kodwa-ke kwabe sekucaca ukuthi lawa kwakungama-squid amakhulu nje kuphela, afinyelela kumamitha ayi-18 ngosayizi, futhi iso lawo elilodwa likhulu kunekhabe elikhulu. Laba bantu banesici esithakazelisa kakhulu, ubuchopho babo bunembobo lapho kudlula khona i-esophagus. Imihlathi yesilwane inamandla amakhulu kangangokuba ingaluma kalula ngamathambo hhayi inhlanzi encane kunazo zonke.
Izilwane zihlakaniphe ngokwanele ukuthi zibe nobuchopho obuzungezwe uhlobo logebhezi. Umzimba uyisiphuku, ngaphakathi kukhona into e-chitinous (igobolondo lithathe leli fomu, isidingo lapho isilwane sinyamalale) futhi izitho zama-cephalopods.
Phakathi kwalaba bantu kukhona nomzalwane ongajwayelekile, obizwa nge-vampire. Lezi zinhlobo zithathwa njengezinto eziphakathi kwe-octopus ne-squid. Izintambo zakhe kuphela ezixhunywe ulwelwesi cishe kulo lonke ubude, futhi umbala womzimba ubomvu ngokugqamile.
Izilwane zihlala kokujula kolwandle olumnyama nasemanzini angajulile (abantu abancane bathanda indlu enjalo). Azihlali endaweni eyodwa isikhathi eside futhi zihlala zihamba. Ngosuku olulodwa nje, zingahamba cishe amakhilomitha angama-30.
Ukudla kwe-squid kufaka izinhlanzi, amanye ama-molluscs, kanye nabamele abancane bezinhlobo zawo.
Izilwane zithola inzalo kanye kuphela ngonyaka. Insikazi izalela amaqanda, kuthi owesilisa amnike amaseli akhe okuzala ngohlobo lwesikhwama. Bese kuzalwa izibungu. Bazobe sebekulungele ukuzala ezabo izingane onyakeni owodwa noma emibili. Ekupheleni konyaka wesithathu wokuphila, isilwane siyafa.
Impilo ye-squid ayiyona "ushukela". Ngoba wonke umuntu ongelona ivila uyazizingela - kusuka kubantu kuya kumahlengethwa nezinyoni. Amandla abo okuhamba ngokushesha, nokuba khona kukayinki akusizi ukuthi kuphenduke inyamazane yomunye othambile. Ukubaphonsa emanzini, badida isitha.
Phakathi kwe-squid, okulandelayo kuthakazelisa kakhulu: i-piglet squid (encane kakhulu futhi ibukeka njengobuso bengulube), ingilazi squid (esobala njengengilazi, kuphela amehlo nezitho zokugaya ukudla)
I-Cuttlefish.
Isilwane asisikhulu kakhulu, ubude baso bungaba ngamasentimitha ambalwa nje, mhlawumbe no-30. Azihlali isikhathi eside, kuze kube yiminyaka emi-2. Le nkampani ayithandwa kakhulu, imvamisa bachitha isikhathi bodwa, hhayi ikakhulukazi begijima besuka kwenye indawo beya kwenye. Lo mthetho wephulwa kuphela uma kufika isikhathi sokukhiqiza kabusha.
Lezi zingenamgogodla zinohlobo lwemidlalo yokukhwelana. Kuyiqiniso, ngokushesha ngemuva kokukhulelwa kwamaqanda, abantu abadala bangathatha umhlalaphansi baye kwelinye izwe. Ngokungafani nama-mollusk amaningi, i-cuttlefish iya kozingela ngaphambi kokuba kube mnyama, kodwa uma ibeka engcupheni yokuba izisulu ngokwayo, izigaxa esihlabathini isebenzisa amaphiko ayo.
Ngokubukeka, umzimba we-cuttlefish ufana nesilinda esicwecwe. Ngaphakathi kukhona uhlobo lwethambo - igobolondo eliguquliwe. Leli bhodi alisebenzi nje kuphela njengesihlangu sezitho zangaphakathi, eligijima ngaphesheya komhlane wonke, kodwa futhi lisiza ukulawula ijubane lokuhamba kwesilwane, ligcwalise amagumbi ahlukaniswe kuwo ngamanzi. Ngokuqondene novalo izinhlelo ze-cephalopod, khona-ke ithuthukiswe kakhulu kunamanye amalungu ohlobo.
Ekhanda le-cuttlefish kunamehlo amakhulu kanye nomhlanga okhethekile abamba ngawo futhi ugaye ukudla. Uma isilwane singekho engozini, izingalo zaso zicindezelwe ngokuqinile komunye nomunye futhi zelulwe, futhi izigaxa zezintambo zihlanganiswe zibe okhethekile. amagumbi.
I-cuttlefish ayithandi ukuba nombala owodwa isikhathi eside, ishintsha kalula imibala yayo. Lokhu kungaba amaphethini ahluke ngokuphelele. Isibonelo, lowo obizwa ngokuthi onemigqa unobuthi obulalayo. Ngaphandle kwalokhu, izinhlobo ezahlukene zemollusc zidliwa ngabantu.
- Uhlome ngezi-8
Unamabhangqa amane wezandla, futhi esisekelweni axhunywe ngokukhethekile. ifilimu - ulwelwesi. Ngaphandle kwalokho, konke kufana namanye ama-cephalopods - i-mantle sac (umzimba) ithambile futhi ayinasimo uma ifika emhlabeni.
Ingwane.
Amehlo makhulu futhi ahlala kumaphrojekthi. Ngaphezu kwalokho, uma kunesidingo, bangahamba kalula futhi bagxile entweni ethile. Kunenqwaba yamaswidi ezintendeni (zingahamba ngemigqa emithathu, futhi inombolo ifinyelela ku-2 000), ziyakwazi ukuthumela amasignali mayelana nokunambitheka kokudla. Ngaphezu kwalokho, bavame ukukhonza njengemilenze, bebathinta, i-octopus islayida ngokoqobo ngezansi.
Izembozo zama-octopus zivame ukuba bomvu nge-burgundy. Kuliqiniso, okuncane okungashintsha. Ngibonga izipesheli. amaseli emollusk angahlangana nemvelo. Isibiliboco esithandwa kakhulu yi-octopus izinkalankala, izinhlanzi, ama-lobster. Uqhwaku olufana nopholi lubasiza ukuthi bamunce konke lokhu. Izinhlobo ezinkulu kakhulu zinesisindo esingamakhilogremu angamashumi amahlanu.
Uma uqaphela umuntu ophuzi ogqamile onemibuthano eluhlaza okwesibhakabhaka esikhunjeni ngenkathi edilika, kungcono ukushiya ngokushesha okukhulu. Ngemuva kwakho konke, phambi kwakho kukhona ingwane enombala oluhlaza okwesibhakabhaka. Ubuthi bawo buyabulala kithina, futhi umhlangano onjalo ungabulala umuntu.
Ukuzala kungukuqala kokuphila kwabancane kanye nokuphela kwabazali babo. Iduna lishona ngokushesha nje lapho likudlulisela kowesifazane ngosizo lwezici. amashubhu isidoda sakho. Okufanayo, nakho, kuzowathwala ngokwawo kuze kube yisikhathi esifanele, aze anqume ukufaka umquba emaqanda. La maqanda kaningi ayizinkulungwane. Njengoba elinde ama-octopus amancane achanyuselwe (lokhu kungathatha izinyanga eziyisithupha), umama naye uya kwelinye izwe.
Njengekhaya lezingwane, kukhona imifantu emadwaleni, emigodini nasezidlekeni, ama-cephalopods angakha kalula, ngoba ahlakaniphe kakhulu. Ikhaya labo lihlale lihlanzekile. Basizwa ukuhlanzwa ngejethi yamanzi, ekhishwa kungazelelwe, futhi ihlanze yonke imfucuza ngokugeleza kwayo. Izilwane zizama ukuthola ukudla ebusuku. Bayalala. Ngendlela, ngamehlo avulekile.
Ukudla okunomsoco
Lapho imollusk ibona isisulu, iyasibamba ngezinsimbi zayo bese isidonsela emlonyeni wayo. Imvamisa kusetshenziswa ubuthi, butholwa yindlala yamathe. Ngenxa yalokho, isisulu siyafa. Ekuvulekeni komlomo kunento ebukeka njengomlomo wenyoni (ngayo, isilwane silimaza isisulu, sisikhubaze, futhi silume izingcezu). Lokhu kubonakala komhlathi ongenamgogodla.
Noma kunjalo, inhlanzi enkulu inzima kakhulu kubo. Ukungenisa ukudla ngaphakathi, isilwane sikugaya nge-radula (kubukeka njengolimi olunamazinyo amancane), atholakala kupharynx. Futhi-ke yonke into ijwayelekile: i-esophagus, ngemuva kwalokho ukudla kungena esiswini, kuqeda indlela yayo nge-anus. Lokhu wokugaya ukudla cephalopods.
Ekudleni kwalezi zidalwa, zonke izinhlobo zezinhlanzi, ama-crustaceans, njll. Kuyaphawuleka ukuthi abadeleli nohlobo lwabo, bayadla. Futhi okuxaka kakhulu ukuthi ama-octopus afanayo angazidla imizimba yawo. Kuyiqiniso, ngemuva kwenqubo enjalo, isilwane ngokungenakugwemeka siyafa.
Inani
Kuyini ukubaluleka kwama-cephalopods? Ngaphandle kobukhulu bayo obukhulu, ama-cephalopods avame ukuba yisisulu sezinye izidalwa eziphilayo uqobo. Ziyingxenye yokudla kwehlengethwa. Ziba yisibiliboco semikhomo ebulalayo nemikhomo yesidoda.
Inyama yeCephalopod nayo iyaziswa ngabantu. Lokhu kungenxa yokuthi icebile kakhulu ngamaprotheni, kepha ngeke uthole amafutha kuwo. Izimayini zenziwa emazweni angamakhulu amahlanu emhlabeni jikelele. Bathanda ikakhulukazi ukunambitha isibiliboco esinje eThailand, e-Italy naseJapane. I-China ayikho ngaphansi komakhelwane bayo.
Zidliwa ziluhlaza, zibilisiwe, zomisiwe, zisemathinini nokunye. Njalo ngonyaka, amathani ayisigidi ama-cephalopods abanjwa ekujuleni kolwandle. Amanetha asetshenziselwa ukumbiwa phansi. Ukubanjwa okuhle kakhulu kuvame ukuba sentwasahlobo nasekuqaleni kwehlobo.
Indlela ekhethekile "yokudoba" ithandwa ezweni lelanga eliphumayo. Izimbiza zobumba zisebenza njengogibe, ngibabopha ngentambo bese ngiziphonsa phansi. AmaMollusks akhuphukela lapho futhi azizwa ekhululekile lapho, ngakho-ke, noma ngabe bezama ukubakhipha emanzini, abajahile ukushiya indawo yokukhosela.
Ngaphezu kokudla okunomsoco, ama-mollusks nawo anenani lobuciko. Uyinki wabo akakhi i-watercolor kuphela, kodwa futhi uyinki. Futhi, umuntu usebenzisa i-octopus ebanjiwe njengesithiyelo. Ngosizo lwayo, izinhlanzi ziyabanjwa.
Futhi manje ngokuthi lezi zingenamgogodla zingalimaza kanjani. Amacala amaningana wokuhlaselwa kwe-octopus aqoshwe emlandweni. Ukwanda okukhulu kwenani labo kuholele ekutheni amakhulu ezidumbu zalezi zilwane agcina osebeni, ngenxa yephutha lesiphepho, noma igagasi eliphansi.
Ngenxa yalokho, imizimba ebolayo yangcolisa inhlabathi nomoya. Ngaphezu kwalokho, ama-octopus amaningi kakhulu aholela eqinisweni lokuthi izilwane ezifakiwe ekudleni kwazo zisengcupheni yokuqothulwa. Imayelana nama-lobster nezinkalankala.
